My biggest problem with it is that it comes overclocked but undercooled. If I don't ramp up the fan & throttle the clock back, I get black screens and the driver will crash. But I have the BFG-tech version, so your mileage may differ

When I turn my pc to standby and wake it up, sometimes the gpu will go into super slomo and will do games at like 10 fps instead of 60, and even youtube won't play at a working framerate. (like 4 fps)what could couse this and does anyone know a solution exept restarting the pc? ( ive got a i7 and sli 285)

this usually happens when your gpu crashes and then recovers and the clocks will be stuck in "safemode" until you restart your computer. i recommend lowering Clockspeed and/or updating to newest drivers
